Abstract
The utility model discloses a piston body used for a shock absorber, which comprises an annular seat body with one end being a seat surface. A piston rod installation hole is disposed in the middle of the seat surface, and cone-shaped orifices are located around the piston rod installation hole. The piston body used for the shock absorber is simple in structure, easy to achieve and capable of greatly reducing damping of the orifices, thereby ensuring shock absorbing effect of the shock absorber and improving work stability of the shock absorber.
Description
Technical field
The utility model relates to the piston field, is specially a kind of piston body that is used for vibration damper.
Background technique
Concussion when vibration damper mainly is used for suppressing bounce-back after the spring shock-absorbing and from the impact on road surface.Through uneven road surface the time, though the shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Vibration damper comprises oil-overflow cylindrical shell, and disposes the piston rod that has piston that stretches in the cylindrical shell, and throttle orifice is arranged on the piston, makes that the oil in two-part space that is separated by piston can complement each other.Mostly the throttling piston hole of existing technology is straight hole, when fluid flows through damping bigger, influence the damping performance of vibration damper.
The model utility content
The purpose of the utility model provides a kind of piston body that is used for vibration damper, is the big problem of the out-of-date damping of piston oil flow of straight hole to solve the existing technology throttle orifice.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of piston body that is used for vibration damper; Include the annular base body that an end is a seat surface, have the piston rod mounting hole in the middle of the said annular base body seat surface, be arranged in piston rod mounting hole annular base body seat surface on every side and have a plurality of throttle orifices; Said throttle orifice is evenly distributed on around the piston rod mounting hole; It is characterized in that: said throttle orifice is a cone shape hole, and the less hole face in throttle orifice aperture is positioned at the seat surface exterior edge face, and the bigger hole face in throttle orifice aperture is positioned at the seat surface interior edge face.
The utility model is simple in structure; Be easy to realize that a plurality of throttle orifice uniform ring are designed to cone shape hole with throttle orifice around the piston rod mounting hole; Increase gradually owing to the throttle orifice aperture like this; Can reduce the damping of throttle orifice greatly, and then guarantee the damping effect of vibration damper, improve the vibration damper working stability.
